Hello Tim,
We have defective Weyerhauser siding that needs to be replaced. We want to put permanent siding on, and we have been told the siders will put insulation on top of the old siding and then put the new siding on top.
Our concern is possible mold and other nasty stuff that may be lurking inside the current siding that will make itself felt after the new siding is applied.
Should the old siding be torn off, or is it acceptable to put the new on top of the old? Thank you very much,
Mary

Mary,
The old siding MUST come off. It is non-negotiable. To say the very least, I am deeply concerned you are not using the right people for this job. If they think it is a good building practice to leave the old siding in place, what other things do they do wrong on a routine basis? You couldn't pay me to use the company you are currently talking with.
